Abstract
The invention discloses a center distance adjusting mechanism for a multi-shaft tightening machine. The center distance adjusting mechanism is characterized in that: tightening shafts are respectively arranged on tightening shaft sliding blocks arranged in the radius direction of a reference circle, and can linearly move on a linear guide rail through the tightening shaft sliding blocks by using the radii of the reference circle as loci; a cam plate capable of rotating in a centered manner is arranged at the position concentric with the tightening machine, and each tightening shaft is connected with the cam plate by adopting a cam follower; and one end of the cam follower is fixedly connected with the tightening shaft, the other end of the cam follower takes a distance adjusting waist hole in the cam plate as a motion track, the motion locus of the cam follower in the distance adjusting waist hole from the bottom of the distance adjusting waist hole to the top of the hole is at the reference circle positions of different radii, and the variation range of the radius of the reference circle is supposed as the center distance adjusting range. Through the center distance adjusting mechanism, the center distance of the multi-shaft tightening machine can be adjusted in a simpler manner so that the multi-shaft tightening machine adapts to different products.
Description
Technical field
The present invention relates to be applied in the multiple-shaft tightening machine that uses in the rundown process of connecting bolt in the parts such as automobile differential, a kind of multiple-shaft tightening machine centre-to-centre spacing governor motion of more specifically saying so.
Background technology
Multiple-shaft tightening machine often need be set to different centre-to-centre spacing for being suitable for the product of different model, but does not have the open report of relevant device in the prior art.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of multiple-shaft tightening machine centre-to-centre spacing governor motion is provided, and makes multiple-shaft tightening machine obtain the automatic adjusting of centre-to-centre spacing with comparatively simple mode, to adapt to Different products.
The present invention adopts following technical scheme for the technical solution problem:
The design feature of multiple-shaft tightening machine centre-to-centre spacing governor motion of the present invention is respectively to tighten axle to be separately positioned on along the tightening on the slide block of reference radius direction setting, and through tighten a slide block can be on line slideway be the track moving linearly with the reference radius; Be that the cam disc that can feel relieved and rotate is set on the concentric position with the tightening machine center, the said axle of respectively tightening is connected with cam disc employing Cam Follower; One end of said Cam Follower with tighten the axle connect firmly; The other end is to be tracks with roll adjustment waist hole on the cam disc, and the movement locus to the top, hole is to be on the reference circle position of different radii from the bottom, hole in said roll adjustment waist hole to be in Cam Follower in the said roll adjustment waist hole; The excursion that reference radius is set is the centre-to-centre spacing adjustable range.
The characteristics of multiple-shaft tightening machine centre-to-centre spacing governor motion of the present invention also are:
The rotation in order to the driving cam dish of cylinder or servomotor is set.
It is annual disk that said cam disc is set, in the interior week of said annual disk, along circumference each spring bearing that evenly distributes.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, convexity wheel disc of the present invention processing is than being easier to obtain high accuracy, so the multiple-shaft tightening synchronism and the high conformity that move, and it is accurate to tighten a center;
2, cam follower transmission efficiency of the present invention is high, the underway heart during apart from adjustment resistance little;
3, the present invention can be set to diaxon, three, four, five or multiaxis more according to actual needs, and is applied widely;
4, the present invention is equipped with cylinder or servomotor as driving power source, can obtain the adjusting of reference diameter more than three kinds or three kinds easily.
Description of drawings
Fig. 1 is a governor motion structural representation of the present invention;
Fig. 2 tightens the axle construction sketch map among the present invention;
Label among the figure: 1 tightens axle; 1a tightens a slide block; 2 line slideways; 3 cam discs; 4 Cam Followers; 5 roll adjustment waist holes; 6 cylinders; 7 spring bearings.
The specific embodiment
Referring to Fig. 1, Fig. 2, the structure of multiple-shaft tightening machine centre-to-centre spacing governor motion is set in the present embodiment:
Respectively tighten axle 1 and be separately positioned on along the tightening on the slide block 1a of reference radius direction setting, and through tighten a slide block 1a can be on line slideway 2 be the track moving linearly with the reference radius; Being that the cam disc 3 that can feel relieved and rotate is set on the concentric position, respectively tighten axle 1 and be connected with cam disc 3 employing Cam Followers 4 with the tightening machine center; One end of Cam Follower 4 with tighten the axle connect firmly; The other end is to be tracks with roll adjustment waist hole 5 on the cam disc 3, and the movement locus to the top, hole is to be on the reference circle position of different radii from the bottom, hole in roll adjustment waist hole 5 to be in Cam Follower 4 in the roll adjustment waist hole 5; The excursion that reference radius is set is the centre-to-centre spacing adjustable range.
In the practical implementation, the rotation in order to driving cam dish 3 of cylinder 6 or servomotor is set; Cam disc 3 is set is annual disk, in the interior week of annual disk, along circumference each spring bearing 7 that evenly distributes.
When 3 rotations of cylinder 6 driving cam dishes; Cam Follower 4 can receive the power along the contact point normal orientation; Under the effect of this power component, Cam Follower 4 and drive is tightened axle 1 along the moving of reference radius direction, and the center of tightening axle 1 changes to the distance in the reference circle center of circle.Tighten axle when moving simultaneously when all, variation has taken place in the reference diameter that is equivalent to a center of tightening, and accomplishes the process that centre-to-centre spacing is regulated.
